Accumulation and Translocation of Heavy Metals in Plants Grown inIndustrially Polluted Fields and Selection of Suitable Species for Phytoremediation

Abstract

newline Phytoremediation is a technique which is eco-friendly and low cost potential strategy newlinefor cleaning up of trace metals from contaminated soils. The present investigation deals newlinewith the accumulation of heavy metals in fields contaminated with industrial pollution newlineand subsequent uptake in different parts of Argemone mexicana, Calotropis procera, newlineCannabis sativa, Solanum nigrum, Solanum virginianum and Dhatura stramonium newlinenaturally grown plants species. Results revealed that in the contaminated site, the newlinemean level of all the metals (Fe,Ni, Pb, Cu, Cr, Cd and Zn) in soil and different parts newline(roots, stem and leaves) of plant species were found to be significantly higher than the newlineuncontaminated soil. The enrichment factor of these metals was found significant. newlineResults showed the translocation ability was better in contaminated sites compared to newlineuncontaminated sites, and these naturally grown plant species Argemone mexicana, newlineCalotropis procera and Dhatura stramonium could be considered as best accumulator newlineof Fe, Cu and Zn which indicates a great performance of this plant for phytoextraction newlineand might be introduced as hyperaccumulator plant. The present findings provide us a newlineclue for selection of plant species, which show natural resistance against toxic metals newlineand are efficient metal accumulators. newlineKey words: Accumulator species, Accumulation, Translocation factor, Enrichment newlinefactor, Industrial effluent, Heavy metals (Fe, Ni, Pb, Cu, Cr, Cd and Zn).
